# Petroleum Engineering+ vs Engineering English

Petroleum Engineering+ and Engineering English are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Petroleum Engineering+ sells 6 in-app purchases, starting at $9.99 per month and Engineering English sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
